Serum 20 AOX+
Combines 20% L-ascorbic acid with ferulic acid to provide antioxidant and anti-aging benefits
Formulated at the precise concentration proven to deliver maximum amounts of vitamin C to the skin, Serum 20 AOX+ is designed to restore and protect healthy looking skin. This lightweight and fast-absorbing serum neutralizes free radicals, defends against environmental damage, and helps prevent accelerated aging.
Studies show that when formulated properly (as all SkinCeuticals antioxidants are), a 20% concentration of L-ascorbic acid provides the maximum amount of vitamin C readily absorbed by the skin.
Formulated with AOX+ advanced antioxidant technology, Serum 20 combines ferulic acid with pure vitamin C at the precise pH and concentration to enhance performance and deliver maximum levels of L-ascorbic acid.
L-ascorbic acid has a reservoir effect, which means it can’t be washed off or rubbed off for a minimum of 72 hours.
The addition of ferulic acid enhances the antioxidant performance of vitamin C.
In the morning after cleansing, apply 4-5 drops to a dry face, neck and chest.
It is normal for vitamin C products to darken after opening due to air and light exposure. Any change in color does not affect the product's efficacy.
